Foundational work has examined adaptive social behavior in animals in relation to the costs
and benefits of group living. Within this context, a “group” of animals represents an …

We assessed social, spatial (using grids of 100× 100, 200× 200 and 500× 500m) and habitat
(vegetation) segregation between sex and age classes in two Alpine ibex populations (Sous …

1. So far, no measure exists to quantify sexual segregation in animal populations. Studies on
segregation have relied on ecological measures of overlap and association to estimate the …

The social organization of the last population of giraffes (Giraffa camelopardalis) in West
Africa was studied between October 1996 and December 1997. Population size increased …

We analysed individual associations between mouflon (Ovis orientalis musimon) observed
during one year in order to find ontogenetic patterns underlying the social structure of the …

How large herbivores track resource quantity and quality through time has formed the core
of an abundance of literature on migratory populations in recent decades. Yet, relating …

Sexual segregation reported in many wild ruminants is generally assumed to result from
either different habitat choices by adult males and females or 'social factors'. In this …

The sociality of cattle facilitates the maintenance of herd cohesion and synchronization,
making these species the ideal choice for domestication as livestock for humans. However …

Several models have recently confirmed the hypothesis that mean group size should
increase with population density in animal species in which groups are unstable. Based …

This study was undertaken to describe the effect of previous acquaintance on aggressive
behaviour in repeatedly regrouped pigs and the nature of interaction between sexes. Four …
